BELL.

SPECIFICATION formingpart of Letters Patent No. 492,779, dated March 7, 1893.

Application filed December 16, 1891. Serial No. 415,214. (No model.)

.To all whom, it may concern,-

Be it known that I, NAHM JUDsoN BUsBY, of Maplewood, county of Middlesex, State of Massachusetts, have invented an Improvemeut in Gong-Bells, of which the following description, in connection with the accompanying drawings, is a specification, like letters and figures on the drawings representing like part-s.

This invention is an improvement on that class of bell shown in United States Patent No. 447,538, dated March 3, 1891, and granted to me.

The object of this invention is to simplify the hammer-actuating train, and the means for winding the spring, and topermit the spring to operate as desired.

I have adapted the bell, herein shown as having its actuating train normally wound 2o up, to be released by or through a slide which acts upon the shaft of the pallet-locking device, the said shaft, or the slide, one or both, having a beveled or cam surface, so that when one is moved across the face of the other the pallet will be unlocked, permitting the train acting on the pallet, to vibrate the hammer until the pallet is again looked.

In this present invention I have combined with the main shaft of a motor or train having a ratchet-wheel, and a train-locking device of some suitable form, and a winding lever and pawl (the latter being of peculiar construction), a pawl-releasing device, whereby, when the winding lever or pawl-carrier, of whatever-form, is moved in one direction,

'the ratchet-Wheel on the main shaft is rotated, the pawl acts, and the spring is wound up; but during the early movement of the `lever 0r pawl-carrier when returning to its 4o normal position, the pawl is released or automatically disengaged from the said ratchetwheel, and immediately the train is held from completely running down by or through the operation of the said locking-device.

Figure l in side elevation, with the gong in section, shows a bell embodying my invention; Fig. 2, a section below the line 0c; Fig. 3, a section below the line Fig. 4, an underside view; and Fig. 5, a detail on the line x2, Fig. 3.

The base A, of any suitable shape and material, has suitable pillar posts a, on the top of which is supported the pillar-plate ot,hav

ing a hub or stand d2, on which is supported the gong 0,3.

The driving-train shown consists essentially of a main shaft b, having a ratchet b', a gear b2 having a detent b3, an actuating spring b4 normally wound up, pinion h5, gear bpinionl bf, and escape-wheel 68. The escapement acts .on a pallet c, fast on a pallet-shaft c', the latter carrying the hammer and-being adapted to be moved by the escapement-wheel whenever t-he train is not locked.

' As a locking device for the train, I have,in

shown acting frictionally against the side of.

the pallet and holding it. locked in engagement with the escapement-wheel, as in Figs. l and 2. The plate d2 has a projection 2, see Figs. l and 2 which is so located as to substantially touch the outerv side of the pallet between its ends, so that when the pallet is locked friction-ally it is impossible for said pallet to be stopped iu a position with the hammer in contact with the gong. The upper end of the shaft d is acted upon by a spring d', while -the lower end of the shaft, see Fig. 5, at a point below the base, is shown as beveled, to be acted upon by a beveled part of a slide-bar d5, represented as provided with a stop or projection 5 and as acted upon by a spring 6, see Fig. 4. The slide has at one end a take-up device 3, shown as a screw eye, which, when an actuating wire connected with said take-up gets slack, the screw may be rotated to put the proper tension upon the wire. of the arrow, Fig. 4, either by pushing or pulling it in any usual way commonly practiced in. actuating door-bells, will act'on the lower end of the shaft d4 and raise it to remove the pin or projection of the locking-device frorn the pallet, when the train being thus unlocked starts to run, causing the escapement to move the hammer.

To wind the motor, I have provided a lever or pawl-carrier g, provided with a peculiar pawl g', shown as acted upon by a spring g2 and as having a tail g3. When moving the lever in the direction of the arrow, Fig. 3, the pawl engages the ratchet-Wheel g4, fast on the The slide, when moved in the directionl main shaft b, and rotates the shaft to wind the spring, and if or whenv the leveris released A and the shaft turned in the opposite direction, a part of the pawl meets the stop g5, which disengages the pawl from the said ratchet, leaving the shaft, whenever the locking-device for the train is released byl or l through the slidebar d5, free to turn under the action of the spring 6.

The bell so far described is very simple in operation and may be readily applied in almost any desired position for a door-bell, or

' may be substituted for any usual form of A ,2. The driving train, a normally operative locking device therefor, a winding ratchet and a rocking winding lever or paWl-carrier having a pawl pivoted thereon to engage said ratchet when the lever is moved forward, combined with a releasing device in the path of movement of, and to disengage the pawl from the ratchet when the said lever or pawl-carrier is moved backwardly, substantially as described.

3. In a bell, its striking mechanism, the driving train therefor, and the normally operative locking device for said train, combined with a movable slide engaging with and to move said locking device into inoperative position to release the train, the operating cord or wire for said slide, and an adjustable takeup between said slide and cord, substantially as described.

In testimony whereof I have signed my naine `to this specication in the lpresence of two subscribing witnesses.

NAHUM JUDSON BUSBY.
